Embedded Systems Conference

BOSTON--(BUSINESS WIRE)--Sept. 5, 2001

Green Hills Software today announced that its INTEGRITY(TM) real-time operating system (RTOS) has been selected by Lucent Technologies Inc., for use in its WaveStar(R) BandWidth Manager.

Green Hills will also provide its MULTI(R) 2000 software development environment, optimizing C/C++ compiler, and multiple communications protocols (TCP/IP, SNMP, DHCP, PPP, FTP, and IP Multicast) for the product.

"Lucent's selection of our INTEGRITY RTOS is a validation of INTEGRITY's high availability architecture and real-time responsiveness," said John Carbone, vice president of marketing at Green Hills. "Only a memory-protected RTOS with fast, predictable response times can deliver the maximum reliability needed for sophisticated, high-availability systems like Lucent's networking equipment."

INTEGRITY is a scalable, ROMable, memory-protected, royalty-free RTOS. Leveraging the hardware memory protection facilities of the PowerPC's Memory Management Unit (MMU), INTEGRITY maximizes security and reliability by building a "firewall" between the kernel and user tasks, preventing errant or malicious tasks from corrupting user data, the kernel, interprocess communications, device drivers and other user tasks. In addition, INTEGRITY guarantees the availability of system resources like the CPU and memory to application processes, making it far more predictable than conventional embedded operating systems.

INTEGRITY features comprehensive networking and embedded Internet support. INTEGRITY supports a robust TCP/IP stack, Web server, Web browser, networking protocols (UDP, DHCP, FTP, and Telnet), routing protocols (NATrouter and RIP) and SNMP management software, all of which are optimized for embedded applications. INTEGRITY also supports Trillium's telecom protocols, including SS7, ATM, Broadband ISDN, Frame Relay/ATM, MPLS, H.323 Control (VoIP), TCP/UDP Convergence, ASN.1 Encoder/Decoder - PER, RTC/RTPC, SIP, SCTP, SS7 MTP Level 3 user adaptation layer, GPRS, 3G, V5 and GR-303, ISDN, Q.930/Q.931, and X.25/X.75.

INTEGRITY is tightly integrated with the MULTI and AdaMULTI(R) 2000 IDE. Together with Green Hills' family of optimizing C, C++, EC++, and Ada95 compilers, MULTI automates all aspects of embedded software development, including editing, source-level debugging, program building, run-time error checking, version control, and code/performance optimization. INTEGRITY also features ISIM, an RTOS simulator that enables programmers to develop and test their code on a PC or workstation without the need for target hardware, and the EventAnalyzer(TM), which enables viewing of system and user events in a graphical display.
